1. A syngas reforming exchanger comprising:
- a vessel comprising an elongated shell having relatively high and low temperature ends;
a shell side fluid inlet adjacent the high temperature end for receiving a hot gas feed;
a tube side fluid inlet adjacent the low temperature end for receiving a reactant feed gas;
a shell side fluid outlet fluidly isolated from the tube side fluid inlet by a tube sheet adjacent the low temperature end for discharging cooled gas;
a tube bundle comprising a plurality of tubes, wherein the tubes have an inlet end secured to the tube sheet for receiving the feed mixture and an outlet end adjacent the shell side fluid inlet for discharging product gas into the hot gas feed to form a gas mixture;
a longitudinal shell-side flow path for the gas mixture through the tube bundle;
a heat resistant refractory lining affixed to an interior surface of the shell about the tube bundle;
an imperforate sleeve at least partially disposed about the tube bundle for directing the gas mixture over the inlet ends of the tubes; and
a discharge annulus defined between the sleeve and the shell slide fluid outlet.

Abstract
A syngas reforming reactor has a shell-and-tube configuration wherein the shell-side fluid flow path through the tube bundle has a longitudinal configuration. The reactor can include a shell-side inlet fluid distributor plate below the lower end of the tube bundle.
